The Futurematic, released by LeCoultre, the American brand of Jaeger-LeCoultre, is the world's first "fully" automatic watch without a winding mechanism via a crown.

The company's half-rotor automatic movement, Cal. 497, is known for its ambitious structure, which includes a "sleep mode" when the watch is removed, and its distinctive design.
